Abstract Manganese selenide (MnSe), as a newly emerged manganese‐based chalcogenide, has recently been considered potential cathode for aqueous Zn‐based energy storage due to its many merits. Nevertheless, unsatisfactory kinetic performance and cycling stability, along with controversial mechanism, hinder commercial application. Herein, the MnSe microspheres Se‐rich vacancies (V Se ‐MnSe) are synthesized, employed Zn‐ion batteries/capacitors (ZIBs/ZICs) first time. Density functional theory (DFT) calculations analyses illustrate that vacancy engineering of enhances active sites, improves electronic conductivity ion transport, reduces adsorption diffusion barriers H + Zn 2+ , endowing V ‐MnSe ZIBs significantly enhanced specific capacity, rate capability, stability. Interestingly, ex situ tests confirm stable existence during whole charge/discharge process store insertion subsequent /Zn co‐insertion. More encouragingly, ‐MnSe//porous carbon (PC) ZICs exhibit an ultrahigh density (178.0 Wh kg −1 ), high power (10 kW eminent cyclic stability (up 10000 cycles). This research offers efficient strategy designing developing high‐performance chalcogenides sheds new insights into their mechanisms.
